I. Core Understanding: What is Tyvek? The Core Requirements for Medical Packaging 

(1) The essence of Teweiqiang: A technological innovation in nonwoven membrane production. 

Trevira is neither traditional paper nor film—it’s high-density polyethylene. HDPE A nonwoven fabric made from fibers produced via flash spinning. Its unique manufacturing process creates a continuous, robust filament structure that combines the breathability of paper, the flexibility of cloth, and the water resistance of film—laying the foundation for meeting the core requirements of medical packaging. 

(2) The Four Core Performance Requirements for Medical Packaging 

• Microbial barrier property: Blocks the penetration of bacteria and spores, ensuring a sterile core. 
• Physical protection: tear-resistant, puncture-resistant, and capable of withstanding external forces during transportation and storage; 
• Sterilization compatibility: Compatible with mainstream sterilization methods, with no performance degradation after sterilization. 
• Cleanliness and Stability: Minimal flaking upon opening, stable performance over long-term storage, ensuring a sterile and clean environment with no risk of contamination throughout the shelf life. 

II. Core Advantages: The Five Key Dimensions of Tewei Qiang’s Adaptation to Medical Packaging 

Compared to traditional medical packaging paper and paper-plastic composite films, Tyvek’s core advantages precisely meet the stringent requirements of medical packaging, specifically as follows: 

(1) The Ultimate Microbial Barrier: Building a Strong, Long-Term Sterile Defense Line 

The continuous filament structure of Tyvek creates a tortuous, permeable pathway that effectively blocks bacterial spores and test particles, offering superior barrier performance compared to commercially available medical packaging papers. Shelf-life studies show that when the packaging remains intact, it can maintain a sterile condition for at least five years—far exceeding the shelf life of conventional paper-plastic bags. 6 One-month validity. 

(2) Ultra-strong physical protection: Reducing the risk of packaging failure 

• Tear resistance: Comparable to medical-grade packaging paper. 8 Double, resistant to rough handling; 
• Puncture resistance: Resists puncture by sharp instruments (such as orthopedic implants and surgical blades), preventing loss of sterility. 
• Moisture and water resistant: HDPE The material prevents moisture from penetrating and protects humidity-sensitive instruments. 

(3) Fully compatible with mainstream sterilization methods: Suitable for diverse scenarios. 

Teweiqiang is compatible with mainstream sterilization processes worldwide, eliminating the need to change packaging materials based on the sterilization method. 

• Ethylene oxide ( EO ) Sterilization: Breathability ensures that sterilizing agents can penetrate and residues can be effectively removed. 
• Gamma rays / Electron beam sterilization: exhibits excellent radiation resistance and maintains stable performance after sterilization. 
• Steam Sterilization: Adaptable to high-temperature steam sterilization under controlled conditions; 
• Low-temperature oxidative sterilization: Suitable for temperature-sensitive high-end medical devices. 

(4) Clean Peeling + Anti-condensation: Safeguarding the Safety of Clinical Environments 

• Cleanliness: Minimizes the generation of airborne particles when opening or operating, thereby reducing the risk of contamination in cleanrooms such as operating theaters. 
• Anti-condensation: The breathable material balances temperature and pressure fluctuations during transportation and storage, reducing condensation inside the packaging and preventing equipment from becoming damp. 

(5) Green and Sustainable: Balancing Practicality with Environmental Protection 

Special Security Pressing ISO 14001 Standard production that can be recycled in accordance with local regulations; the new renewable products utilize certified renewable raw materials and electricity, significantly reducing carbon emissions, through— ISCC PLUS Certification enables full supply-chain traceability. 

III. Mainstream Models and Application Scenarios: Precisely Matching Medical Needs 

DuPont offers multiple Tyvek® models tailored for medical applications, with key differences lying in thickness, weight, and strength, thereby meeting diverse needs—from standard consumables to high-end implantable devices.
